Sounds like a lot of work as cheap as engines are these days. I am running the Ascendancy G5 and it's been great. Price point is pretty nice too.

Can anybody help me with this and tell me wich rod is the best for me? Thanks

That would be a G5 rod as it has a slight update compared to the GRP tuned rod. The lower bushing is made of harder material according to Rody.

G5 conrod
 
Where can I buy a rod for a g5?

If you can't find a G5 rod then you can use a Tecnopower B01 or TQ speedlab .21 rod aswell (same rod as the G5).

Grp rod
 
Hey ambros I was looking up some of the rods for sale on ebay and omnimodels has a duratax rod that look very close to the grp I know the materials may not be as good but for the price I think is worth triying it, the lenght of it is 37.5mm from top to bottom and 30mm from center of the holes the only problem with it is that does not say the size of the holes I will soon take my engine apart to measure the lenght of my rod an if it is the same I will ask omnimodels for the size of the holes,this may be a cheaper way to go even if it will have to be replace sooner. This rod is only 13.0 dollars shipped

The rods have to be the excact same size tho, else you will get timing differences in your engine. The bushings have to be the exact size aswell. For the trouble i'd try and find a GRP tuned, G5, TQ or an TecnoPower B01 rod ;)

A Main has TecnoPower rods if i'm not mistaken :tire:

I know a-main have them but they want 80 for the tecnopower rod thats why I am looking for other options thanks ill let u know I talk to the people at duratrax and they said they will get back with the hole dimensions cause they did not have them at the moment hopefully they come true and they are the same for the money I think is worth trying

MR21-BO1A
 
Evening guys. Anyone know where to get carb needle o-rings for a Ninja MR21-BO1A? I'm also curious if any of the engines, in the Technopower line up, parts are interchangable (bearings and other internals). Any response appreciated. Thanks!

Tecnopower lsn will fit. You ordered the air screw. That's why they are different. Check the part under b01 u will see they look the same(the one u broke) Hope this helps.
